![]() ![]() Soluble copper compounds form the largest threat to human health. Most copper compounds will settle and be bound to either water sediment or soil particles. Copper is often found near mines, industrial settings, landfills and waste disposals. Other examples are mining, metal production, wood production and phosphate fertilizer production.īecause copper is released both naturally and through human activity it is very widespread in the environment. A few examples of human activities that contribute to copper release have already been named. Examples of natural sources are wind-blown dust, decaying vegetation, forest fires and sea spray. As a result soils may also contain large quantities of copper after copper from the air has settled.Ĭopper can be released into the environment by both natural sources and human activities. ![]() Copper in air will remain there for an eminent period of time, before it settles when it starts to rain. Copper enters the air, mainly through release during the combustion of fossil fuels. ![]() Rivers are depositing sludge on their banks that is contaminated with copper, due to the disposal of copper-containing wastewater. This basically means that more and more copper ends up in the environment. The world's copper production is still rising. Due to this, copper quantities in the environment have increased. The production of copper has lifted over the last decades. For instance it is applied in the industries and in agriculture. The main long established copper alloys are bronze, brass (a copper-zinc alloy), copper- tin-zinc, which was strong enough to make guns and cannons, and was known as gun metal, copper and nickel, known as cupronickel, which was the preferred metal for low-denomination coins.Ĭopper is ideal for electrical wiring because it is easily worked, can be drawn into fine wire and has a high electrical conductivity.Ĭopper is a very common substance that occurs naturally in the environment and spreads through the environment through natural phenomena. Most copper is used for electrical equipment (60%) construction, such as roofing and plumbing (20%) industrial machinery, such as heat exchangers (15%) and alloys (5%). In moist air it slowly forms a greenish surface film called patina this coating protects the metal from further attack. It is found in group Ib of the periodic table, together with silver and gold. It is softer than zinc and can be polished to a bright finish. It is malleable, ductile, and an extremely good conductor of both heat and electricity. It reflects red and orange light and absorbs other frequencies in the visible spectrum, due to its band structure, so it as a nice reddish color. + 0.522 V ( Cu +/ Cu ) + 0.345 V (Cu 2+/ Cu )Ĭopper is a reddish metal with a face-centered cubic crystalline structure.
